introduction
The Atmospherix AS and Atmospherix A20 are
high quality in-ceiling loudspeakers featuring
fully sealed back-boxes to control and
maximise bass response, whilst keeping out
dust and other ceiling inhabitants.
The Atmospherix A20 employs an acoustically
optimised front baffle angled at 20 degrees
allowing its sound output to be projected
towards your primary listening area. The
standard Atmospherix employs a flat front
baffle for uniform sound coverage in all
directions. (figure 1)
applications best suited to Amospherix AS
The wide uniform coverage of the
Atmospherix AS makes it the ideal choice
for 2 channel stereo and background music
applications. Its uniform coverage is ideally
suited to any applications where the listening
area is not confined to a specific part of the
room. For examples, hallways, dinning rooms,
office spaces and bedrooms and multipurpose
rooms. (figure 2)
introduction
Atmospherix A20 Atmospherix AS
figure 1
applications suited to Amospherix A20
The ability of the Atmospherix A20 to project
sound toward your listening primary listening
area makes it ideally suited to home cinema
applications (figure 3). Dialogue will become
more articulate, music will have better
definition and surround effects will become
more involving and realistic. The A20’s ablility
to direct more sound towards the listener
results in less sound reflecting off walls
and other surfaces in the room creating a
clearer, more three dimensional soundstage.
The A20 may also be useful for background
music applications where the speakers must
be placed near a side wall for aesthetic or
structural reasons. In this application the the
A20 can be used to project the sound towards
the centre of the room.

installation
before you begin
Please read the disclaimer on page 2
!
of this manual.
• Refers to page 3 of this manual and
discuss with your local Krix distributor, or
installation consultant, to determine the
best location for your loudspeakers. Be
sure to check for any obstructions, such as
electrical wiring, plumbing, stud work or
air conditioning ducts before commencing
the installation. (figure 4)
!
figure 4
• Also ensure that there is enough ceiling/
wall space to accommodate the speaker
enclosure.
connecting
To ensure optimum performance it is
important that your speaker system is
connected properly:
!
Turn off all electronic equipment and
disconnect from the power point.
• Follow the connection instructions
supplied with your amplifier, CD/DVD, hard
disk recorder, video player etc.
• Install speaker cable in wall or ceiling
cavity, or run cable along wall surface.
Allow approximately 300mm of excess
cable to facilitate loudspeaker installation.
• Follow the connection instructions
supplied with your amplifier to connect
the speaker cables to amplifier. Take care
to assign the same cable colour or trace to
the positive (+) connector on the amplifier
as the positive (+) connector on the
speaker.
• Prepare speaker cables for connecting to
speakers by neatly stripping cable ends.
installation
• Once the correct placement the speakers
has been determined, use the cardboard
insert marked ‘template’ (from the internal
packing) to trace the required cut-out onto
the ceiling/wall. (figure 5)
• Drill a hole inside the marked cut-out.
Using a fine gyprock saw, cut around the
inside of the marked cut-out. (figure 6)
• Remove the circular offcut and insert the
speaker to check the hole is the correct
size. Enlarge the cut-out if required.
!
Atmospherix A20 only:
Determine the correct orientation for
your speaker. A small arrow embossed
in the front baffle marks the direction
of the speakers primary coverage. It is
recommended that this arrow is aimed
towards your primary listening area for
best results. (Figure 3, Figure 7)
• Pull the stripped speaker cable through the
ceiling/wall opening. Push and hold down
the positive (+) red binding post on the
speaker and insert the positive (+) wire
through hole in post. Take care to assign
the same cable colour or trace to the
positive (+) connector on the amplifier, as
the positive (+) connector on the speaker.
Repeat connection process with the
negative (-) black binding post and the
negative (-) wire. (Figure 8)
• Ensure all mounting clamps are swung
back against the speaker enclosure
(Figure 8), so that the speaker can be
easily inserted into the ceiling cut-out.
Once the speaker has been located in the
ceiling/wall, use a Philips head screwdriver
to tighten all mounting screws. As the
screws are tightened, the mounting
clamps will automatically swing out over
the gyprock and clamp the speaker in
place. Be careful not to over tighten the
screws, as this may strip the clamp, or
crush the gyprock surface. (Figure 9)
• Gently fit the magnetic grille to the front
of the speaker housing. (Figure 10)
If the grille requires painting it is
!
recommended that the grille is painted
attached to the speaker after installation.
Use a small foam roller with a light
coverage of thin paint to avoiding
blocking the holes in the grille.
Care should be taken to eliminate loose
!
strands of wire that may be present a
short circuit hazard.
